Last weekend was my first time at a shooting range, I'm totally new with guns. My friend bought a Sig Sauer and I tried. There were 3 of us so we took turns. On the first round I had no problem. But on my second round it jammed almost every single shot (by jamming I mean the shell not ejecting and was stuck inside). My friend (who has experience with shooting a gun) went up after me and he was fine, no jamming. So what did I do wrong? The way I held the gun? I only put one finger on the trigger and my left hand was supporting at the base. The way I pulled the trigger? But the action is so instantaneous I don't see how I can do wrong? By the way the gun was brand new so it's not dirty. Bullets are cheap though, but that doesn't explain why when my friend shot it it doesn't jam.
